Your Chromebook is plugged in, but the battery isn't charging. That doesn't automatically mean you need a new charger. Start with the connections, then work through the checks below to separate charger trouble from battery problems and charging settings.
Check for damage before plugging it in again
Inspect the charger and cable for cuts, breaks, or fraying. Damaged charging equipment needs replacement before you continue.
Look at the Chromebook's charging port for physical damage or oxidation. A damaged port or a swollen or deformed battery needs manufacturer support for repair or replacement.
Check your model's manual for the required adapter specifications and supported charging ports. A USB-C connector alone does not mean the port supports charging.
Use the original adapter and cable, or a replacement that meets those requirements.
Reconnect the charger and check the outlet
Give the power connection a fresh start using Google's recommended order.
Verify that the wall outlet works. If you use an extension cord, check that it is switched on, or try another outlet.
Disconnect the charger from both the Chromebook and the wall.
Reconnect the charger to the Chromebook first, making sure the connection is fully inserted.
Plug the charger into the wall and check that all power connections are secure.
Leave the Chromebook connected for at least 30 minutes before trying to turn it on.
Test a compatible charger to isolate the fault
A charger swap separates adapter trouble from a Chromebook charging problem.
Connect a known-working adapter that meets your Chromebook's requirements. If charging begins, that points to the original charging equipment.
Test the suspect adapter with another compatible device. Compare the results to narrow down whether the adapter or the Chromebook's charging connection needs attention.
On a Samsung Chromebook with multiple charging-capable USB-C ports, test each supported port individually. Note whether charging works through one port but fails through another.
If you use a Type-C dongle with a Samsung Chromebook, reconnect the dongle.
Reconnect its attached devices.
Check the battery icon again.
Give a depleted battery more time
The first 30 minutes aren't the end of the road for a deeply discharged battery. For HP Chromebooks with deep-discharge symptoms, leave the AC adapter connected for the recovery window HP specifies, from 10 minutes to 24 hours, with occasional Power-button checks for startup.
If your Samsung Chromebook starts but still has charging or power problems, give it at least one hour of charging with the Chromebook turned off before testing again.
For a Chromebook previously placed in Google's long-term storage state, power it on with its charger connected to a working power source. Opening the lid or pressing Power alone cannot start it in that state.
Read the indicator lights according to your manufacturer's instructions. On Samsung models covered by its diagnostics guidance, red means charging, green means fully charged, and blue means powered on. Those meanings do not apply across all Chromebook brands.
Remove an 80 percent charging limit
On supported Chromebooks, Charge limit deliberately stops charging at 80%.
Select the time.
Open Settings > System preferences > Power.
Beside Optimized charging, select Change. Adaptive charging delays a full charge, while Charge limit caps charging at 80%.
Select Done after checking the selected option.
For consistent full charging, turn off the Optimized charging toggle under Settings > System preferences > Power. Availability and control depend on your Chromebook's hardware and administrator settings.
For a one-time override of an Adaptive charging hold, select Fully charge now in its notification.
Restart, then try a hardware reset
Try these after checking the charger and connections; a hardware reset carries a risk of losing some files in Downloads.
- 1.If the Chromebook responds, select time > Power > Restart.
- 2.Reconnect the charger and check whether charging resumes.
- 3.If charging still fails, turn the Chromebook off before attempting a hardware reset.
- 4.On most Chromebook laptops, hold Refresh and tap Power. Some models require different reset instructions, so check Google's model-specific hardware-reset guidance if this sequence does not apply.
- 5.Release Refresh when the Chromebook starts, then check charging again.
- 6.For a Chromebook tablet, use this instead of the laptop key sequence: hold Volume up + Power for at least 10 seconds, then release.
Run battery diagnostics and get support
If your Chromebook runs ChromeOS 90 or later, open time > Settings > About ChromeOS > Diagnostics. Its Battery information includes battery health, cycle count, and electrical current.
On Samsung Chromebooks with Diagnostics, open Diagnostics > System > Battery.
Disconnect the charger.
Select Run Discharge test.
Reconnect the charger.
Select Run Charge test.
If the charging test fails or cannot run, recheck the battery level, charger, and connections.
Once power is restored, connect to Wi-Fi.
Open time > Settings > About ChromeOS > Check for updates. Allow any available update to download.
Restart when prompted.
If charging still fails after compatible-adapter testing and the applicable reset, contact the Chromebook manufacturer with your model and test results. For a school or work Chromebook, contact your administrator or device-support team. They also handle restricted charging-optimization controls.
Frequently Asked Questions
Why won't my Dell Chromebook charge through an Apple USB-C dongle?
Dell documents a charging incompatibility between the Apple USB-C Digital AV Multiport Adapter and the Latitude 5300 2-in-1 and 5400 Chromebook. Google and Dell are not developing a fix for it. To test the charging connection, remove the dongle and connect a supported charger directly.
Should I Powerwash my Chromebook if it won't charge?
Powerwash is a late step for persistent software problems and requires working power. It erases local user data and cannot repair a physically failed charger. Back up local files before using it. School and work users should contact their administrator.
Does a blinking red light mean the charger is broken?
A blinking red light alone does not establish a charger fault. On Samsung Chromebooks covered by its charging guidance, it indicates battery depletion or charging startup. HP documents a red indicator as battery communication failure, so check the meaning for your manufacturer and model.
Can battery health tell me whether the charger is working?
A battery-health percentage alone cannot confirm that the adapter, charging port, and battery are all working properly. Compare it with charging-test results and a test using a known-working compatible adapter.
